ABSTRACT: The condensation of various thiosemicarbazones with methyl thiophene-2-carboximidate afforded the corresponding intermediates 2a–2h. Subsequent cyclization of the latter compounds with hexamethylphosphorous triamide constitutes a new route to the synthesis of novel highly functionalized thiadiazaphosphole derivatives 4a–4h. This method offers significant advantages such as efficiency, high yields and mild reaction conditions.
One-pot and catalyst-free synthesis of thiosemicarbazones via multicomponent coupling reactions

experimental part, p. 2090 - 2093 (2009/09/05)
A novel and efficient procedure for the synthesis of thiosemicarbazones has been achieved via a multicomponent and catalyst-free reaction of phenyl or p-chlorophenyl isothiocyanate, hydrazine, and aldehydes or ketones. The method afforded 20 thiosemicarba
